Gruffalo, father and son

The most endearing monsters of children's literature are back on the big screen. It is never very good for a Gruffalo, father or son, to show himself in the deep dark wood. He might be chased by the Grande Méchante Souris. But between a Gruffalo and a mouse, which of the two is the scariest? Based on the illustrated books by Julia Donaldson and Axel Scheffler.
